Original application led May 23, 1916, Serial No. 99,310. Divided andthis application filed. March 18, 1918. Serial No. 223,059.

To all whom it may concern:

Be it known that I, LESTER L. KELL, a citizen of the United States, anda resident of St. Louis, Missouri, have invented certain new and usefulImprovements in Cord- Adjusters, of which the following is aspeciication containing a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof. Y

My invention relates to improvements in cord adjusters, and thisapplication is a division of my application for improvements in swings,filed May 23, 1916, Serial Number 99,310.

The object of my invention is to provide a cord adjuster which may beproduced at a relatively low cost; which offers relatively greatresistance to cord movements; which requires relatively little eifect toeffect an adjustment of the cord and which is practically unbreakableand possessed of pleasing appearance. y

My improvements consist in the novel construction, arrangements andcombinations of elements which ,will be fully, clearly and concisely setforth in the following specification, denitely pointed out in my claimsand illustrated by the 'accompanying drawings, in Whichi Figure l is anelevation of a cord adjuster embodying my invention.

Fig. 2 is a view similar to Fig. l taken from a diametrically oppositeview point.

Fig. 3 is a vertical sectional elevation taken on the line3w-3 of Fig.2, with the cord omitted.

Fig. 4 is a vertical sectional elevation taken on the line 4--4 of Fig.3 and showing the arrangement of the cord, and

Fig. 5 is a sectional plan taken on the line 5 5 of Fig. 3 showing thearrangement of the cord.

Referring by numerals to the drawings 6 designates the body of theadjuster, which is preferably formed out of a single piece of wood andof spherical shape as shown.

Mechanically and functionally such designated material and shape are notessential, as obviously, metal, ceramics, glass and so forth may besubstituted for the wood, and likewise the body may be formed circular,square, polygonical or oblong, sectionally, in a plane at a right angleto the trend of the cord and of square, oblong,

elliptical, oval, conical or pyramidall exterior. Inasmuch, however, asthe adjuster is designed for use along the length of a swing suspensioncord or rope I `nd the spherical exterior, which presents no angles, tobe most comfortable to manual grasping andl the least likely to inflictor suffer injury.

As best shown in Fig. 3 there is formed in the body 6, and diametricallythereof along its Vertical axis (when used on a vertical cord, as in aswing, or its horizontal axis when used on a horizontal cord such as aclothes line) a bore or opening 7, open at the surface 8 of the body andextended to a point therewithin between the center of the body and asurface point diametrically opposite the open end just recited, and of adimension capable of receiving a cord length doubled upon itself, asshown in Fig. 4. From the said point within the body, that is, from theinnermost end of the bore 7, and leading to and open at the surface S ata point diametrically opposite the open, outer end of the bore 7, thereis a bore 9, which is of a size less than the bore 7, and capable ofreceiving only a single cord length, as shown in Fig. 4.

f As best shown in Fig. 3 there is a bore or opening 10, open at thesurface 8 at a point, intersected by a line drawn through the open endsof the bores 7 and 9 and belting the body, and which bore 10 opens intothe bore 7. As shown in Fig. 5, the bore 10 is of a transverse dimensioncapable of receiving a cord length doubled upon itself.-

Alining with thelongitudinal axis of the bore l0 andextending into thebody 6 from the bore 7 to a point inside the body is a bore 11, of asize capable of receiving only a single cord length and from theoutermost end of the bore 11 open to both the bore 11 and the surface 8is a bore 12 of a size capable of receiving a knotted end of the cord.

In the surface, belting the body 6 and intersecting the bores 10 and 12is a groove 13 whose depth is preferably less than the sectionaldimension of the cord.

In the formation of the bore l2 of a greater dimension than the bore 11a shoulder 14 is provided which serves as an abutment for the knottedend of the cord to hold the cord against movement in one direction inthe bore 12, and likewise by forming the bores 11 and 7 and the bores 7and 10 in right angular relationship the points 15, 1G and 17 areprovided within thel body and the points 18 and 19 at the surface, whichserve with the surface of the groove 13,. to resist corda movements.

The threading of the cord may progress from either of its ends Yand forthe-purpose of this illustration I will describe it asproceeding fromthe end 2O which leads to an oi'feiheadl suspension means (not shown)and as 4employed ina swing.

rI his end 20 of the cord is inserted downwardly through the bore 9 andbeing sectionally of the approximate dimension of the bore makes such afit therein vespecially at the surface surrounding the bore as topreclude the possibility of pinching the fingers, skin or garments ofaperson using the swing. From'the bore 9 the cord end is passeddownwardly through the bore 7 to engageover the pointv A15, thencethrough the bore 10v to the 'surface 8, where it engages over the point1S and thence belts the body, occupying the groove 13. The cord is thenthreaded again inthe bore 10 from the surfaceSinwardly and engaged overthe point 19, thence from the inner end aof the bore 19 is turneddownwardly and extended through thel bore 7 and engaged over the point16, thence outside the bore 7 where it is doubled upc-n itself to vformthe bight 21,

l as shown in Fig. 4; and again extended into thebore 7 to the'bore 11,engaging over `the point 17 and thence through the bores 11 and 12,whereupon the cord end is knotted,

as at`22, and'retraoted or drawn so that the knotted end is seated inthe bore 12 against the shoulder 14.

It is obvious that the cord is drawn over a number of points both on theexterior and interior of the body of the adjuster `and that it alsoengages throughout a considen able 'portion of v'its length the exteriorsurface of the adjuster body, and that regardless of the shape of suchexterior surface considerable surface friction is provided. However, Iprefer, as stated, to employ a groove which sectionally conforms to thecord to increase the surfaceI friction area'as well as to act as' almeans to hold the cord against .grotesque irregularity around theadjuster body.

It will be readily apparent that Vupon the Y Iapplication of tension tothe cord end 20 through the several bores.

Having thus described my invention, what I claim as new therein anddesire to 4secure by Letters-Patent is:

1. A Vcord adjuster ycomprising' va body having right angle openingstherethrough and a groove belting the adjuster and interL seeting saidopenings.

2. A cord adjuster formed from a single, solid piece of material andprovidedv with relatively angular bores 'therethrough and a continuousexterior groove belting the body and intersectingl certain ofthe bores.

A cord adjuster lcomprising a'body having means within its interior forholding a Cord end, a pair of openings leading to the exterior of thebody and substantially aliiied with thel tension line of a cord to'beextended therethrough and 'an opening within vthe body communicatingwith the 'pair of openings and'leading to the exterior'of the body at apoint on the exterior removed' from the" intercoinmunieatin g within theadjuster body and certain of said bores'havingwithin their lengthsdiametrijcal reductions 'substantially as shown and for thepurposesstated.

A cord adjuster formed from a single,

solid piece ofinaterialfand provided with bores open at the exteriorofthebody and intercolnniunicatingv within 'the adjuster body, *certain of'said bores having within their lengths diametrical reductions and therebeing a groove beltiiigk thev exterior surface of the bodyI and'Aintersecting certain of said bores.

6.*In 'combinatioirwith a" spherical body provided withbores open attheexterior of thebody andiiiiteroominiinicating within the body, certainof 'which' 'bores having `within their lengths diametrical reductionsanda groove belting the 'exterior'suiface Aof the body andintersectingfat'fleast one of said bores, a cord having ajknottedend'seated in one of tlieboifesaiicl-lield against movement by reasono'f one of the diametrically reduced portions of the bore, said cordbeing doubled in vone 'of the bores and extended around thev body insaid groove, said Vcord being doubled in a second bore and'provided witha bight outside 'said second boreand said cord extended through a thirdbore to' project from the'body.
